Density Training

Density Training - Training to increase workload in specified amount of time aka more reps week to week. I find density training to be more beneficial when using tools that provide limited weight or no progressions.

Would it be possible to substitute some of the sandbag and kettlebell movements (namely where the weight is pressed overhead)such as the lumberjack press, with a section of log? I have availability to actual sections of log (about three feet long, approx 60 lbs).
